ASUS Republic of Gamers (ROG) has introduced the Poseidon GTX 780 with DirectCU H2O, a new graphics card with a hybrid thermal solution that enables efficient cooling by either air or water.

The new card is powered by the latest NVIDIA GeForce GTX 780 GPU. With DirectCU H2O on board offering users the ability to cool either by air or water, ROG Poseidon GTX 780 achieves running temperatures that are up to 24°C lower than reference designs - that's up to 140% cooler for a faster gaming performance.

ROG Poseidon GTX 780 is also loaded with ROG technologies including dust-proof fans for increased card longevity, die-cast thermal armor for improved cooling in the crucial MOSFET area, DIGI+ voltage-regulation modules (VRMs) with black metallic capacitors power design for stability and reduced noise. The new card also comes with GPU Tweak, a software that squeezes maximum performance from the GPUs, offering real-time graphics tuning and live streaming.

A custom vapor chamber is in direct contact with the card?s GPU for faster heat dispersal, while copper heat-pipes and extended cooling fins further transfer heat out and away from the card. According to Asus, with water cooling, Poseidon GTX 780 achieves up to 24°C-lower running temperatures than reference designs - keeping the GPU cooler when using GPU Boost 2.0. With air cooling, Poseidon GTX 780 achieves up to 7°C-lower running temperatures than reference.
